I'm going to be purchasing a used android soon. It's an already rooted Samsung Galaxy S2 on 4.2.2 Jelly Bean. I would just like to verify that it works with the Galaxy S2 on 4.2.2. And also, when clicking the downloader link (I plan on purrchasing it today or tomorrow.) how do I know the price of it? Or how to unlock the full version? And do I need this "Busybox" or anything else to install it? And can it be installed via web browser on the android without syncing with a USB to PC? And one last thing, you don't NEED one of those custom rams to run this right? I believe the GS2 I'm purchasing has default/stock ram or whatever you want to call it.
